I've got 6 chalices in my tank. While my tank is quite bare I hope to eventually have a zoanthid garden with a handful of chalices. I've been slowly increasing my led light intensity by 1% per week. Started at 60% and hoping to Jumpstart my zoanthid growth with more light. So about a week after my last increase (currently sitting at 64%) my mummy chalice lost all color. I dropped it to the sand bed. The next day my watermelon chalice did the same thing. All other chalices and corals look fine. No temperature, ph, or salinity spikes. I did a full battery of tests and showed a slight dip in alkalinity at 8.5 when I usually have around 10.5 to 11. I've since done a water change. Tonight I noticed my mummy and watermelon chalices still have a slight feeding response with some very small tentacles out. Color has not returned. Any ideas?
